Application filed December 22, 1.925. Serial H0. 76,957. I

This invention relates to an assembling apparatus, and more particularlyto an apparatus for assembling relay spool elements.

Conventional types of electro-magnetic relays may comprise a centralcore memberv upon which the relay windings are wound,

with spool heads or flanges positioned on the core at each end of thewinding to secure the winding against longitudinal displacement on thecore. Heretofore it has been the practice in some instances to assemblethese heads uponthe core by performing various operations manually whichnecessitated, for example, the individual selection of spool elementsfrom a source of supply and a number of subsequent. manual operations toproperly assemble the'elements thus selected.

The primary object of the present invention is to facilitate andaccelerate the production of assembled spools by providing aself-contained, durable, and eflicient machine.

to automatically select spool elements from sources ofsupply andsubsequently to perform the operations necessary to complete the properassembly of said elements.

In order to obtain these and other objects in accordance with thegeneral features of he invention, an apparatus is provided havinghoppers for retaining supplies of spool end members or heads and amachine designed to retain a supply of spool cores. A

mechanical feeding mechanism is provided which selects spool heads fromtheirrespective hoppersand advances them into position to besubsequently assembled with a companion core member. .Another feedingmechanism, functioning contemporaneously therewith, transfers amemberfrom the magcent to the head. These assembled spool elee ments arethen advanced to the receiver. head of a device which applies aprotective coatassembling apparatus disclosing an embodiment of theinvention, the assembling ram thereof being shown in its retractedposition and the containerof the lacqueringIHGQhanism in itscorresponding lowered position; Fig. is a detailed view of aconventional fiat type electromagnetic relay core adaptedto be fed intothe machine shown in'Fig. 1; Fig. 3 are details of spool ends or headsadapted tobe assembled with the core shown in Fig. 2;

Referring to the drawings wherein like immerals designate similar partsthroughout the various figures, there is provided an elongated machineframe or base 10 and a pair of hoppers 11 supported at the upper endsofsleeve members 12 mounted 1n brackets 13 secured to the rear wall of thebase.

Revoluble within each sleeve 12 is a vertical shaft 14, the upper endthereof having a suitable hand wheel 15, and the lower end thereofhaving a ratchet wheel 16 secured thereto. A pulley 17 loosely mountedupon the shaft 14 immediately above the ratchet wheel 16 carries a pawl18 designed for operative engagement with the ratchet wheel 16 upon ro-V tation of the pulley 17 (see. Fig.13). By

this construction the shaft 14 may be free 1y rotated independently ofand in the same direction as the pulley 17,'by manipulating the handwheel 15. A circular plate 19 in the bottom of the hopper 11 is securedto the shaft le bymeans of a pin 2O extending through an, annularshoulder formed centrally of the plate 19. A plurality of conveyor lugs21 are formed in the plate 19 midway be tween the wall of the hopper andthe pe riphery of a disk member 22 resting on the plate 19, said lugsbeingspaced to accommodate spool ends or heads 28 similar. to the typesdisclosed in Figs. 3 and 5. The upper surface of the disk 22 is inclineddownward- 1y from its central portion to its periphery and it will beunderstood that when a rotary movement is'imparted to the shaft 14either by manual manipulationof the handle 15 or by power applied to.the pulley 17, spool surface of the hopper wall.

outwardly along theinclined surface of the disk 22 with the result thatthey willb'ecome lodged in the annular channel formed between theperiphery of the disk and the inner Once lodged within this channel,each head will seek to align itself between adjacent lugs 21 upon theplate 19, and as a consequence thereof will be moved in a circular pathprovided by the channel until they reach the lower end or entrance of achute 2A. These chutes 2 1 are in clined upwardly from the bottom of thehoppers at the rear thereof, extending vertically to a'point at whichthey curve. forwardly and then downwardly, terminating at their otherlower extremity in a spool head loading mechanism 25, the operatingcharacteristics chutes 24, and'in this connection it is to be understoodthat the rotation of the plates 19 is such-that the resulting speed withwhich the heads are advanced through the chutes will be in excess ofthat required to keep the loading mechanisms 25 sufficiently suppliedwith said heads. This excessive speed in the feeding operation is merelyto insure a sufliciency of the spool heads supplied tothe loadingmechanisms 25 during the operation of the machine. It will be apparentthat unless somemeans'were provided to take care of an overflow of headsfed into the chutes, the continued rotation of the disk 19 would beprevented after the chutes had been entire- 1y filled. In order to meetthis condition, an opening 26 (Fig. 1) is provided in the front sectionof each chute 241 on the side nearest their respective hoppers and asthe spool heads 23 pass through the chutes at their normal rate ofspeed, the velocity is suficient to carry each head past the opening 26and thus function uninterruptedly throughout the operation of themachine.

. Referring now to Figs. 10 and 13 it will be observed that a flangedbearing member 28 is mounted on the rear wall of the base 10 me 'diallyof the ends thereof and is secured to the base by bolts 29 extendingthrough the flanged portion of the bearing member. This bearing member28 supplies a mounting for a. main drive shaft 30 revoluble within abushing 31 pressed within said bearing member. A cam 82 mounted at theforward end of the drive shaft30 is designed for operative engagementwith a roller 33 carried on the underside of a carriage member 34. Thiscarriage member is horizontally reciproca'ble in gu'ideways 35 providedin a pair of spaced guide bars 36, which are secured at one end to theupper surface of the forward wall of the base 10 by machine screws 37(Fig. 5) andat their opposite ends to the upper surface of the bearingmember 28 by screws 38. A coil spring 39 housed within a pair oftelescopic sleeves 40 and 41 interposed be tween the rear end of thecarriage member 34 and a vertical arm 42 mounted on the bushing 31 atthe rear end of the bearing member 28, serves to yieldingly preserveengagement between the roller 33 and the cooperating surface ofthe cam32. In Fig. 10 the spring 39 is shown as holding the carriage 34 in itsforward position and itwill be obvious that as the cam 32 continues torotate, the roller 33 will be actuated rearwardly against the action ofthe spring 39. The telescopic sleeves 40, 41 and their companion spring39 maybe readily removed when desired by merely telescoping the sleevessufficiently to unseat them from the carriage 34 and the arm 42.

Mounted upon the carriage 34 is a carriage block 43 (Figs. 10, 11, and13), the forward reduced portion thereof having a longitudinal 'slot 44formed centrally thereof to receive an adjusting screw 45 threaded intothe carriage member 34. A pair of screw slots 46 are formed in the rearportionof the carriage block 43 and are designed to receive companionscrews 47 threaded into the carriage member 34. By this arrangement ofscrew slots, the carriage block 43 is adapted to be adjustably mountedlongitudinally of the carriage member 34. The back end of the carriageblock 43 is formed with a rearwardly extending bracket 48 which suppliesav shelf fora rectangular guide member 49;

An elongated guideway 50 formed within the guide member 49 is designedto receive the closed portion of a U-shaped rod 51, the extremities ofwhich are engaged with one. of the cooperating parts of each spool headloading mechanism 25 about to be'desc'ribed.

The spool head loading mechanisms 25, positioned at the lower extremityof each chute 24 are designed to contemporaneously transfer thelowermost spool head from within each chute to a recess 52 formed oneach side of the carriage block 43 (see Fig. 11), when the carriagemember 34 upon which the block is mounted, reaches its rearward positionas hereinbefore described. Referring to Figs. 16 and 17 it will be seenthat the chutes 24 are comprised of two sections, one being abar 53having a channel 54 formed therein. said channel being substantially thesame in cross-section as the transverse section of a spool head 23. The

other section is a covering strip 55 of relatively thin material,traversing the channel 54 and suitably secured to the bar 53. Loaderbrackets 56, secured to the guide bar 36 by bolts 57, supply ananchorage and support for the lower extremity of each chute 24, thechutes being secured to the brackets 56 by screws 57 The lower extremityof each chute 24 is similarly apertured to provide a mounting for acylindrical turn table 59, that portion of the turn table lying withinthe ch anneli54; having a channel 60 milled therein forming lugs 61 oneach side thereof, said channel being milled to a depth and widthcorresponding to the dimensions of the channel 54. When the channels 60assume a vertical position as disclosed in Figs. 16 and 17, thelowermostspool head 23 (dotted lines Fig. 17) in each chute 24 willbecome lodged in its respective channel 60 between the guide lugs 61thereof with the lower end of each head 23 resting upon a pin 62 securedto the turn table 59. The loader brackets'56 like the chute bars 53serve as mountings for portions of a reduced diameter of turn tables 59.A ring 63 having a pressed fit upon the outer end of each of the turntables prevents longitudinal displacement of each turn table and guidesthe same as it rotates within the corresponding bracket 56 and LlOLI 53.Axially positioned within each turn table 59 is an ejector plunger 64,the inner end thereof being enlarged to form a head 65 normally seatedwithin the inner end of the turn table. A spring 66 coiled about eachplunger 64 and interposed between the outer end of the com panion turntable 59 and the forwardly ex tending arm of a spring 67 reachingthrough the outer end of the plunger serves to yield-' ing thecorresponding movements of the carriage block'43, said reciprocationserving to imparta relative reciprocating movement to the turn-tables59. Thus, when the carriage block '43 reaches its limiting forwardposition, the rod 51 will have rotated the turn tables 59 into thepositions shown in Figs. 15

to 18, inclusive, namely, with the channels 60 vertically disposed andforming a continuation of the chute channels 54. Upon the returnrearward movement of the carriage block 43 the guide member 49 is again?LII1Q(l 1nto'engagement with the rod 51 and when the carriage block hasreached its'limiting rear-' ward position, the turn tables 59 will havebeen rotated through an angle of 90 with the channels 60' horizontallydisposed and adjacently coinciding. with respective recesses 52 in thecarriage block 43. With the turn tables in this position the spoolmembers carried therein between the lugs 61areready to be transferredfrom the turn tables into the recesses 52 of the carriage block 43. Asthe carriage block approaches the completion of its rearward movement itengages with rollers 68 mounted upon the terminal of a rearward- 1yinclined arm of each coil spring 67, said springs being coiled aboutvertical pins suitably mounted uponv the bracket ,56. The movement ofthese arms acting through the medium of the spring 67 causes theoppositely disposed arms of the springs 67 secured at their terminals tothe plungers 64, to effect the inward movement of said plungers with theresult that the spool heads carried within the turn tables 59 aretransferred to the adjacent recess 52 in the carriage block 43.

When the carriage block starts on its for ward movement each of thespool heads thus lodged within the recesses 52 are carried for wardlyintoposition to be threaded by a spool core member 69 of the typedisclosed in Fig. 2. Suitably secured to the uppersurface of the base 10near one of the loading mech- 'anisms 25 is a spool core magazine 70magazine 70 in a vertical position with one of thelugs 73 bearing uponthe surface of a guide bar 74 and the lower end of the smaller head 71resting upon the upper surface of a lower guide bar 75. The core members69 sli'de freely within the magazine 70, the lowermost core member beingcarried by gravity into association with a positioning fixture 76' Fig.6), which is adapted to tip the core member from its vertical positionwithin the magazine to a horizontal position upon an assembly ramdescribed. I V

The pos1t1on1ng fixture 76 comprises a 77 in a manner about to behorizontal U-shaped frame 78 longitudinally disposed immediately abovethe assembly ram 77 and' securedin position-by a bracket 79' mountedupon. the upper surface of the base 10. Within the frame 78 and securedto the front side thereof is a fixed stop 80 which is similar in shapeto a stop'finger 81 pivoted to the rear side of the U-shaped frame 78 bya stud 82 and is adapted to be engaged by the upper surface of the ram77 when it is advanced. The stud 82 extends inwardly beyond the frame 78and supports a coil spring 83'which retains the stop finger 81 in itsnormal position (dotted lines Fig. 6) with a lug 84 mounted on thefinger 81 engaging with the rear upper edge of the has been removedtherefrom.

frame 78 when the assembly ram 77 occupies its retracted position (Fig.1), disengaged from the finger. lVith the finger 81 in its normalposition disengaged from the ram zine 7 0 passes between the side of themagazine and the finger 81, the upper end of the fixed finger 80 servesas a rest or support for the underside of the head 72 of the core 69,with the smaller head depending slightly below the plane of the uppersurface of the ram 77. To prevent the core member 69 from beingprematurely tipped to a hori. zontal position, a hinged gate 85supported at the upper extremity of an arcuately shaped arm 86 securedto the closed portion of the U-shaped frame 78, serves to prevent theupper end of the core from from falling away from the magazine '70without the application of a tipping force which is sufficient toovercome the opposing weight of said gate 85. It will be understood thatwhen the core member 69 is in this ver tical positiomthe assembling ram77 'is in its retracted position, it being reciprocable in a guideway 87provided in the upper surface of the base 10. The reciprocation of theram 77 is occasioned by the rotation of the cam32 through the medium ofan adjustable connecting rod 88 interposed between a crank pin suitablymounted on the front surface of said cam and a depending bracket carriedby the ram. As the ram 77 advances, it is first carried into contactwith the pivoted finger 81, said finger being elevated to the 7 positionshown in Fig. 6 with the upper end thereof carried into proximity withthe side of the magazine 7 0 and upon continued movement of the ram thedepending tip of the smaller head 71 is engaged by the advancing end ofthe ram. As awresult, the core 69 is tipped to a horizontal positionwithin the fixture 7 6, with the head 72 resting within the frame 78adjacent to the closed end thereof. 7 V

The lowermost ornext following core mem-.

ber within themagazine is prevented from passing. between the finger 81and the side of the carriage 70 until the core member now lying upontheram 77 within the frame 78 Asthe ram 77 is again moved toward itsretracted position the head 72 of the core member 69 resting thereon,engages with the closed end of the frame 78 withthe result that saidcore member is precipitated to the upper surface of the base 10 with thehead 72 thereof positioned immediately in front of the head end 'of theram. A pair of arcuately shaped fingers, pivoted to the base 10 adjacentto oppo site sides of the assembling ram 77, operate to yieldingly gripthe. corners of the head 72 and properly position the shank of the coremember 69 when said core is advanced by the return movement of ram 77.Upon the return of the rain 77 the advancing or head end thereof iscarried into contact with the head 7 2 of the core member 69 and saidcore is subsequently threaded through C0111- panion spool heads in amanner about to be described. a

As the ram 77 approaches the limit of its advancing movement as shown inFig. 6, the carriage block 43, mount-ed upon the carriage member 3%.will occupy itsforward position as shown in F ig.'10. Slots 89 providedin the carriage block 43 medially of the recesses 52 (Fig. 11)correspond in width to elongated apertures 90 Fig. 3) formed in thespool heads 23 and coincide therewith when the heads are lodged withinthe recesses 52.

A forwardly extending portion 91 of the lower extremity of the strip ofthe chute 2e positioned near the magazine (see Figs. 6 and 18) and thehead end of a swedging mechanism 92 positioned adjacent to the side ofthe carriage block 43 on the opposite side of and in parallelism withsaid extending strip portion 91, serve as lateral guides to retain thespool heads 23 in their respective recesses 52 when said recesses aremoved forwardly away fromthe loading mechanisms 25. A slot 93 providedin the strip portion 91 similar to the slots 89 formed in the carriageblock 43 permits the advancing head 71 of the core member 69 to bethreaded through the aperture of the spool head 23 within the recess 52nearest to the advancing head of the ram 77. After passing through 71enters a chamber 94: .(Fig. 11) formed within the carriage block 43 andslides over the inner end surface of a fixed guide plate 95 secured tothe front wall of the base 10 by bolts 96 (see Figs. 6 and 10). As thecore 69 advances along the guide plate 95 it is directed to the aperture90 of the spool head 23 carried in the recess 52 on the opposite side ofthe carriage block a8 and when the rain 77 completes its forward strokethe first threaded spool head will be snugly fitted against the largerhead 72 of the core member 69 and the second threaded'spool head will beproperly positioned at the base of the head 71 (Figs. 2 and 41),. As theassembly .ram 77 approaches the completion of its advancing stroke theswedging mechanism 92 operates to secure said last mentioned spool headin position upon the core head 71 in a manner about to be described.

The swedging mechanism 92 includes a cylindrical body member 97 clampedagainst a block 98 on the upper surface of the base 10 by tighteningbolts 99 (Figs. 1 and reaching through a. cap member 100. A charging ramrod 101 6) housed within the body 97 is formed with a semi-cylindricalhead 102 at its inner end and. is threaded at its 0p-- posite end toreceive a collar 103 provided with a shoulder 104:. A locking bolt 105is threaded into the collar 103 to lock it in any desired position uponthe rod 101. Interposed between the collar 103 and the head 102 of therain rod 101 is a sleeve 106 sli'dable upon the rod 101 and formed withan an-' nular shoulder 107.- Between the shoulder 107 of the sleeve 106andthe shoulder104e of the collar 103 is a coil s'pring108 and betweenthe collar 107 and a. washer 109 (Fig. 7) slidable upon the rod 101 is asecond and stronger coil spring 110, the washerxbeinr heldnor mallyagainst the head 102 by the spring 110.

Threaded into the outerend ofthebody 97 is a tension .sleeve'lll. theshoulder 107' of the sleeve 106 being normally held in abutting relationwith respect tothe inner end of the tension sleeve 111 throughthe mediumof the spring 110. The upper half of the inner or head end of the body97 is designed to receive a die block 112, which is secured to the bodyby a machine screw 113. The inner. end portion of the head 102 ofthe-ram rod 101 is reduced in size and is provided with atrans- 216formed on the face of the bloclr112 dotted lines Fig. 7).

r A charging bar'll? (Fig. 6 is designed for engagement at its upper endwith the underside of the head 102 and is pivoted at its lower extremityto one end of an arm 118,]oivotally securedv at its opposite end to thebase 10 by means of a stud 119. A spring secured at one end totheunderside of the upper portion of the base 10 is connected at itsopposite end to the extremity of an arm 121 rigidly secured to thecharging bar 117. A roller 122 is mounted in a forked arm 123 whichforins a. continuation ofthe end of the-connecting rod 88 from the pointof pivotal connection 124ton the charging bar '117 during a certain partof the cycle of rotation of the cam 32. When theroller 122 is in adisengaged position with respect to the charging bar 117., the bar willassume the dotted position shown in Fig. 6 through the action oft-hespring 120, and it is to be understood that when the bar occupies thisposit-ion the head 1020f the ram rod 101 will occupy its advancedposition toward the head end of thebody 97 due tothe action of thespring 110 acting upon the washer 109 which is in operative engagementwith said head 102. As the cam 32 rotates in the direction shown by thearrows (Fig. 6) and the roller 122 is brought into contact gaging stop127.

' the upper extremity of the bar engaging with the head 102 causes thehead to be moved outwardly against the action of the spring 110 and theconsequent movement of the collar 103 carried at the opposite extremityof the ram rod 101 permits the spring 108 to expand. The spring 110 ischarged in this manner until the roller 122 engages with the cam surface124 of the-charging bar 117 at which time said charging bar experiencesa downward throw, which causes it to become disengaged from the head102. Upon such disengagement, the charging force stored up within thespring 110 acting upon the washer 109 results in the head 102 beingcarried inwardly with great force. This driving force exerted by thespring 110 will be effective against the head 102 until the movement ofthe washer 109 is suddenly arrested by striking a shoulder 125 (Fig. 7formed within the body 97. The inertia stored up within the head 102will continue to carry" it inwardly after the anovement of the washer109 has been arrested and it is this driving force, effected by theinertia stored upwithin the head "102, which is employed tosimultaneously swedge the opposite sides of the head 71 ofthe coremember 69 positioned between the die member 116 as shown in dotted linesFig. 7. The spring 108 which is compressed during the sudden inwardadvance of the head 102 serves to quickly, retract the head after theswedging operation is completed andthjereby efiectively withdraw the diemembers 116 sufficiently to clear the smaller head 71 of the core 69 asthe assembled spool .is advanced toward a lacquering fixture denotedgenerally by the numeral 126.

After the spool heads 23 have been positioned upon the core member 69and the swedging of the head 71 is completed, the carriage block 43begins to move rearwardly. The assembled spoolis prevented from beingcarried rearwardly in the carriage block 43 by means of the inner end ofthe guide plate 95 which is turned upwardly to form an en- This stop 127engages with the edge of the shank portion of the core 69 as thecarriage block 43 moves rearwardly and thus the spool heads 23 areliberated from their respective recesses 52and the core 69 is liberatedfrom the slots 89 in said carriage block. A channel 128 formed on theupper side of the carriage block 43 (Fig. 11) has a bar member 129hingedly mounted, therein by means of a pin 130 (Fig. 10) traversing thechannel 23at the rear end thereof. The opposite end of thebar 129 isformed with a recess 131 and a rod 132 extendingtransversely of the bar129 within said recess is secured at its opposite ends in companionejector fingers 133, said ejector fingers being pivoted at their innerextremities to the 'sides of the bar 129 by means of a pin 134. Teeth135 formed ment oi said carriage block.

along the lower edges of the ejector fingers 133 are designed-to engagewith each end of the shank portion of the assembled spool cores as theyare advanced along the surface of the guide plate 95. The hingedconstruction of the bar 129 as well as the hinged construction of thefingers 133 permit the teeth 135 to slide over the cores superimposingthe guide plate 95 as the carriage block 43 is carried rearwardly. Inthis connection itwill be noted that a coil spring 136 is suitablymounted upon the upper surface of the hinged bar member 129 which isadapted to exert a yielding downward force against the bar 129 so as toeffectively lodge the teeth 135 behind the core members in position toadvancethem upon the return forward movetooth 135 of each ejector finger133 engages with the assembled spool core at the outer and advances thespool core to receiver head 137 of the lacquering fixture 126. p

The lacquering fixture 126 comprises a container 138 mount-eduponthelower end of a vertically slidable bracket 139 (Figs. 1, 5, and 10), andsecured thereto by a wing bolt 140 as shown in Fig. 1. i The bracket 139is pro vided with. a pair of aligned slots 141 and 142 arrangedlongitudinally thereof and a pair offcompanion guide bolts 143 and 144extending through the slots 141 and 142, respectively, said bolts beingsecured at their inner ends to the front wall of the base 10. Theupperportion or the bracket 139 is inclined from the vertical andcarries a guide pin 145 which reaches into a cam slot 146 formed in theshank of the spool receiver head 137. The inner extremity o1 a. stubshaft'147 extending transversely of the receiver head 137 and providinga pivot therefor is mounted in the upper end of a fixed bar 148supportedby the guide bolts 143 and 144. A pair of integral andangularly related bell cranks 149 and 150 are revolubl'e upon the guidebolt 144, the extremity of the crank 149 being pivotally mounted withina' slot 151 provided in the upper side of the'slidable bracket 139. Theextremity of the crank 150 is pivotedto one end'of a link 152, theopposite end of which has a slotted connection ith a stud153 securedtothe depending arm of a strap 154 which is mounted at its inner endupon the assembling ram 7? by bolts The horizontal reciprocation of theram 77 results in a relative vertical. reciprocation of the bracket 139through the medium of the bell crank 149 pivoted within the slot 151,the belly crank 150 and the link 152 connecting said crank 150 with thestrap 154. Vertical movement of the guide pin 145 on the bracket 139within the cam slot 146 in the shank of the receiver head 137. causesthe head. tobe swung through an angle of 90 about thestub shaft 147. Thereceiver head 137 is provided The outermost 'endot the forward movementof the fingers Ill) with a transverse opening 156 and a yielding fingermember 157 and when the head is swung upwardly into its horizontalposition as shown in Fig. 1 the opening will lie in the path of the lugs73 of the outermost core member upon the guide plate 95. The head 72 ofthe core member will be advanced between the tip of the yielding finger157 and a companion tip 158 formed on the receiver head 137 of the lugs73 will enter the opening 156 (Fig. 1). It will be observed that thelimit of the upward swing of the receiver head 137 is determined by theshank of the head engaging with a stop pin 159 mounted in the bracket139. After the assembled spool has been fed to the receiver head 137 bythe teeth 135 at the outer extremity of the ejector fingers 133 as abovedescribed, the aovancement of the ram 7 7 will cause the receiver headto be swung downwardly, thereby carrying the core of the spool memberlodged therein to a vertical position as shown in 5 and 21. The bracket139 will continue to move upwardly after the core,.carried by thereceiver head 137 has attained the vertical position shown in Fig. 21and during this portion of the upward movement of said bracket thecontainer 138 is carried into operative engagement with the smaller head71 of the vertically positioned core member.

Referring to Fig. 10 it will be seen that the container 138 is providedwith a cover 160 clamped thereto by screws 161. The central portion ofthe cover 160 is formed with a neck 162 which has a plunger 163vertically slid'able therein. This plunger 163 is pro- Vided with adepending double rack bar 16-1,

which is engaging a pair of oppositely disposed pinions 165, each pinionsupporting the end of a radial arm 166. Each of these arms has anarcuate member 167 hingedly mounted therein, yieldingly held in positionwith respect to the arm 166 by a leaf spring 168 and adapted to passupwardly through companion apertures 169 in the cover 160 when theplunger 163 is actuated downwardly. A spring 170 encircling the neck 162of the cover 160 cooperates with-a pin 171 in the plunger 163 tonormally retain the plunger in its upper position with the arcuate members 167 swung downwardly within the container and immersed in a bath ofsuitable protective compound such as lacquer.

After the core ofthe assembled spool is swung to a vertical position bythe receiver head 137 as hereinbefore described, the continued upwardmovement of the bracket 139 carries the plunger 163 into engagement withthe tip of the smaller head 71-of the assembled spool core (Fig. 10).This results in the upward swinging of the arcuate members 167 throughthe apertures 169 to bring the tips of the members contemporaneouslyinto contact with the opposed surfaces of the core head 71 adjacent tothe spool head mounted The leaf spring 168 mechanism will beparticularly effective in such instances to supplant the portions of theprotective coating on the core, which may be removed during the swedgingoperation, with a coating of lacquer. Following this lacqueringoperation the spool. carried in the receiver head 137 is swung back toits horizontal position and is subsequently ejected from the receiverhead b the next advancin s oolmember. 1

Referring to Figs. 10, 19, and 20, it-Will be observed that rotation isimparted to the drive shaft 30 from a source of power (not shown)through the medium of a fly wheel 172 which is revoluble upon a bearingmember 17 3 keyed to the drive shaft 30 and a pair of levers 174 carriedby the fly wheel, designed for engagement with a driving flange 175formed integrally with the'bearing member 17 3. These levers 174 arepivoted at one end to the web of the. fly wheel17 2, the opposite freeends of each lever being connected with one end of a spring 176. Thesprings 176 function to yieldingly retain a tapered tooth 177 formedmedially of eachlever, in operative engagement with. a companion notch178 formed in the periphery of the driving flange 175. Obviously, theforce exerted by the spring 176 to retain the teeth 177 within thenotches 178 will be efiective within force necessary to propel theworking parts of the machine under normal operating conditions. If forany reason the working parts of the machine are subjected to duty orstresses which are in excess of those occasioned during normaloperation, the teeth 17 7 Will be forced away from the notches 178against the force of the springs 17 6. A flange member 179 slidable uponthe bearing 173is secured to one end of a pair of oppositely disposedguide pins180 which reach through the web of the fly wheel 172 and aresecured at. their opposite ends to adislr 181 slidable upon the hub ofthe fly wheel (Fig. 20). Springs 182 encircling the guide pins 180 andinterposed between the'disk 181. and'the ada certain limit, whichis'dependent upon the j acentsurface of the web of the fly Wheel 172,

cause the face of the flange 179 to yieldingly bear a 'a"inst the ti asof rotrudin lock ains a l e 183 mounted medially of each of the levers174, when the teeth 177 areengaged with their respective notches 178. V7hen the levers 174 are swun outwardl towards their.dise1'igaged'position the beveled portion of the end of the lock pins183 clear the flange member 179, thereby permitting the springs 182 toelevate levers 174 and to carry the face or the flange member toward theopposing face of the driving flange 175. The teeth 177 are thus helddisengaged from the driving flange 175 with the lock pins 183 bearingagainst the periphery of the flange 179, the fly wheel 172 thereby beingfree to rotate upon the bearing member 173 without supplying apropelling force to the drive shaft 30.

r In order to impart a rotary movement to the driving shaft it isnecessary to move the flange 179 and the disk 181 against the act-ion ofthe springs-182 to, permit the springs 176 to carry the levers intooperative engagement with the. driving flange 17 5.

lVIounted upon .the hub of the cam 32 is a brake drum 184 ofconventional design (Figs. 10 and 12) and housed therewithin is an an- Vnular brake shoe 185- designed for-frictional engagement with the innersurface of the brake drum. By lowering a lever arm 186 (Fig. 13) whichis pivoted at its inner end upon a longitudinal shaft 187 threaded intothe flange of the bearing member 28, a second stub shaft 188 reachingthrough the flange of the bearing member 28 is rotated by a pair ofconnecting links 189 and 190. The link 189 is slotted to permit thelever arm 186 to be raised. without imparting rotation tothe stub shaft188. The inner end of the shaft'188 terminates in the form of arectangular head between the ends of the annular brake shoe 185. 12mm itwill be understood that a slight counter clockwise rotation of the shaft188 will expand the shoe against the drum 184.. The braking effect ofthe shoe 185 against the drum occasioned by lowering the lever arm 186will be sufficient to cause the teeth 177 of the lever 174 to becomeautomatically disengaged and thereby render the impelling force of thefly wheel172 ineffective. A spring 191 secured to the link 190 serves tomaintain the lever arm 186 in its normal. horizontal position. r

The pivoted end. of the lever 186 is formed integral with a sleeve 192(Fig.10) provided with cam teeth 193 at the end thereof. A

' second sleeve 194 longitudinally slidable and nonrotatable upon theshaft 187 is also formed with cam teeth 195 designed to he engaged bythe cam teeth 193 of the sleeve 192, the rear portion of the sleeve 194being enlarged to form a yoke 196which 1s frictionally engaged withaface of the disk-181.

\Vhen'the levers 174 are moved to their disengaged positions, the flangemember 179 and disk 181 are subsequently actuated forwardly (to the leftFig. 10) by the action of the springs 182 with the result that thesleeve 194 is likewise moved forwardly and the teeth 195'on said sleeveare interlocked with the cam teeth 193 on the sleeve 192. By rais ingthe lever arm 186 the teeth 1193 on the sleeve 192 cooperate with theteeth 195 on .the sleeve 194 to actuatev the latter to the right (Fig.10) and thisresu-lts in the flange member 179 becoming disengaged fromthe.

lock pins 183.

A lock washer 197 (Fig. 10) secured to v the rear end of the drive shaft30 by a threaded bolt 198 prevents the bearing member 173 from beinglongitudinally displaced upon the drive shaft. A drive pulley 199mounted upon the outer end of the bearing 17 3 is connected with thepulleys 17 at the lower end of the vertical hopper shafts 14 through themedium of a belt 200 as shown diagrammatically in Fig. 14. A pair ofidler pulleys 201 may be employed to properly guide the portion of thebelt 200 extending between the drive pulley 199 and the pulleys 17.

In the operation of the machine,j spool heads 23 are supplied to thehoppers 11 and core members 69 are supplied to the magazine through theupper end thereof. The core members will occupy a vertical positionwith-- in the magazine asshown in Fig. 8 and-will slide downwardlytherein by the force of with the lowermost: core in position to be actedupon by the positioning fixture 7 6 at the lower end of the magazine.The shafts 14 are rotated by the hand wheels 15 ina direction to advancethe spool heads 23 within vthe hoppers 11 upwardly into-the chutes 24until that portion of each chute extending from the loading mechanism'25 up to the overflow openings 26 is filled with spool heads. Power issupplied to the fly wheel 172from a suitable source and the- "lever arm186 is raised to engage the teeth 17 7 with the notches 178 of thedriving flange be understood that the assembling ram 7 7 will bepositioned at the limit of its advancing stroke as shown in. Fig. 6.Continued rotation of the cam 32 willresult in the rearward V movementof the carriage block 43 and'a relative retraction of the'ram. At thistime in the cycle of operation the turn table 59 within each spool headloading mechanism '25 is positioned as shown in Figs. 15 to 18,inclusive, and permits the lowermost spool head in each chute to becomelodged within the channel 60 \VhlCllIlOW assumes a vertical position.

As the carriage block 43 approaches its limitin'g rearward position bythe engagement of r the raised surface ofthe cam 32 with the the uppersurface of the ram 7 7 and the upper end of the finger moves away fromthe side of the magazine 7 O sufficiently to permit the lowermost coremember 69 within the magazine to drop into position within the fixture76, with the lower edge of the core head 72 resting upon the upper endof the fixed finger 30 and the upperedge thereof immediately adjacent tothe free end of the hinged gate 85. When the carriage block 43 reachesits forward position, the ram 77 will have started upon its advancingstroke and as it continues to advance, the core'member 69. is tippedfrom its vertical position Within the fixture 7 6 to a horizontalposition upon the upper surface ofthe ram within the U-shaped' frame 78.The apertures:90of the spool heads 23. now lodged within the recessesofthe carriage block, are in position to be threaded by a core member,but from the foregoing it will be obvious that no core member has as yetbeen positioned to be advanced and assem-- bled by the head of the ram77. Therefore, it will be understood that-this first pairof spoolheads'thus advanced by the carriage tion is precipitated to theuppersurface ofthe base 10, immediately ahead of the advancing ram. Thesecond pair of spool heads are carried forwardly by the carriage block43 and as the ram 77 starts upon its advancing stroke, the apertures90-ofithespools in the block will lie in-the path of the advancing corehead 71. As the ram .approaches'the completion of its advancing-stroke,the swedging mechanism 92 functions to form burrs'upon the opposed edgesof the core head 71 adjacent to the spool head just threaded thereon;thereby rigidly securing said spool head in position. A spool assemblyis completed, as described above, during each subsequent cycle ofrotation of the drive shaft .30 and the spools thus assembled areadvanced step by step. along thesurfacc of the guide plate 95 by theteeth 135 of the fingers 133 engaging with the shanks of said spools.The

outermost assembled spool upon, the guide" plate 95 is fed intothe'receiver head 137 of the lacquering mechanism 126, when the headoccupies the raised position shown in Fig. 1.

During the advancing movement of the as- I sembling ram 77, the receiverhead is swung downwardly and the core member carried therein moved to avertical position. The arouate members 167 within the lacquer container138 are then actuated and a globule of lacquer is subsequently appliedby the tips thereof to the swedged portions of the core head 71. Duringthe retracting movement of theram 77 the spool thus treated is swungupwardly into its original horizontal position and sub-.

sequently ejected by the next advancing spool.

If the cooperating parts of the machine are subjected to stresses inexcess of those .experienced during the normal operation thereof, themechanism positioned'at the rear end of the drive shaft 32 willautomatically operate to render the propelling force of the fly wheel172 ineffective and the machine inoperative until thenecessaryconnection is effected again by lowering the lever arm 186.v Tostop the machineduring, the course of its operation, it is onlynecessary to lower the lever arm 186, and thereby cause the brake shoe185 to frictionally engage with the brake drum 184 with suflicient forceto operate the disengaging mechanism above mentioned.
